I have a 1984 Vanagon automatic.  No power steering.
I screwed up the steering knuckle by letting the grease cap fall off in
the wheel cover
and loosing all the grease.

According to ETKA I can use part numbers:

251407312, or
251407343c
251407631
24-e-023827
251405645b

This is for the right side which I assume is the passanger side.

Should I call some of the junk yards on the web page or does someone
out there have one?

Thanks
John.
